1Z0-047 ve 1Z0-051 Arasındaki Farklar

Oracle'ın SQL ile ilgili 2 tane sertifikasyonu bulunmakta. 

Biri Oracle Database SQL Expert (1Z0-047), 

diğeri de Oracle Database 11g: SQL Fundamentals I (1Z0-051). 

İlki başlı başına bir sertifika olmasına karşın, ikincisi ancak Oracle Database 11g: Administration I (1Z0-052) sınavı geçilirse bir sertifika değeri kazanmakta. 

Oracle Database SQL Expert (1Z0-047) sınavı aşağıdaki konuları içermektedir. Oracle Database 11g: SQL Fundamentals I (1Z0-051) sınavı ise sadece kırmızı ile işaretlediğim konulardan oluşmaktadır. İki sınavda da %60-%70 arasında bir başarı beklenmekte.
